In a little less than a month I'm going to be starting at Marquette University, and want to put together an EDC I'll carry around with me in my backpack. Since I'm going to be commuting, I just need the stuff to get me through the day, along with a little extra in case of some wrinkles! (minor emergencies, etc.) So far I've thought of: First aid kit, with latex gloves and a mouth barrier (self-explanatory) A small (5-7 inch) relatively flat crowbar (might need to pry a window open for egress, or elevator doors) Knifeless Leatherman Fuse (it's a college campus, so I think knives are going to be frowned upon) Surefire G2 Inova X5 Keychain can of pepper spray or similar Whistle 50-100 feet of paracord A couple carabiners Any suggestions for a backpack/bag in which to lug around all this stuff, along with my laptop, textbooks, notebooks, etc.? Any other ideas? Any suggestion for specific equipment? Anything you'd recommend substituting for something else? Anything on that list you think is unnecessary?
